*For dual-channel configuration (3), you may:

•install identical DIMMs in all four sockets

•install identical DIMM pair in DIMM_A1 and DIMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

•install same size DIMMs in DIMM_A1 and DIMM_B1 (blue sockets) and another same size pair in DIMM_A2 and DIMM_B2 (black sockets)

Memory frequency/CPU FSB synchronization

This motherboard supports different memory frequencies depending on the CPU FSB (Front Side Bus) and the type of DDR DIMM.

CP U FSB	DDR DIMM Type	Memory Frequency
800 MHz	PC3200/PC2700/PC2100	400/320*/266 MHz
533 MHz	PC2700/PC2100	333/266 MHz

*When using 800 MHz FSB CPU, PC2700 DDR DIMMs run only at 320MHz (not 333MHz) due to chipset limitation.
